Hi Thomas, Xueming,
This change is breaking multiple sample applications, testpmd was also broken
but already fixed by Qi [1].
Indeed this patch should update sample applications and testpmd as well when
doing an ethdev API update, also should update release notes "API Changes" section.
We can fix sample applications for rc2, but same thing also can hit users.
Or for this release we can remote returning error, instead update log message to
error. Next release add the return and change log message back to debug.
What do you think?
